Wosb Sole-Source Threshold

WOSB and EDWOSB sole-source contracts can be awarded without competition up to $4.5M for services and $4.5M for manufacturing (adjusted periodically for inflation). The contracting officer must determine that the award can be made at a fair and reasonable price and that no responsible WOSB/EDWOSB can be identified through competitive procedures.

Example: The Simplified Acquisition Threshold or a fiscal-year budget measure.

Where this matters in federal contracting

Wosb Sole-Source Threshold is a measurement used in federal contract evaluation, source selection, oversight, or performance management. For example: Example: The Simplified Acquisition Threshold or a fiscal-year budget measure. Understanding Wosb Sole-Source Threshold matters because evaluators use metrics like it to compare proposals quantitatively, score past performance, set award-fee outcomes, and decide who gets the next option year. Contractors who track how Wosb Sole-Source Threshold is calculated — and what target values look like in their NAICS or service area — write proposals that are concrete and defensible instead of generic and easily dismissed. Wosb Sole-Source Threshold also has implications for contract administration: getting the calculation methodology wrong post-award is a common source of disputes and contracting-officer modifications. Pair Wosb Sole-Source Threshold with the related metrics above to see how the federal government composes evaluation criteria into source-selection narratives.
